Rachel Hart KNH 411 11/27/2012 Acute Hepatitis CS I. Understanding the Disease and Pathophysiology 1. Several specific versus that cause hepatitis have been identified. Describe the following characteristics of each. Characteristic Likely mode of transmission Hepatitis A HAV Oral-fecal route Symptoms Dark urine, fatigue, itching, loss of appetite, lowgrade fever, nausea and vomiting, pale or clay colored stool, jaundice Population most often affected More likely in adults who travel internationally, use IV drugs, live in a nursing home, work in the health care setting Means of reducing exposure Receiving the HAV vaccination Treatment No special treatment, rest, adequate nutrition and fluids are Hepatitis B HBV Transfusions of blood or bloodderived fluids or instruments that have come into contact with blood There may be no symptoms, some may feel sick for a period of days or weeks, and some may be very ill Hepatitis C HCV Sharing needles, having unprotected sexual contact with a person who has the disease Abdominal pain or swelling, pale or clay colored stool, dark urine, fatigue, fever, itching, jaundice, loss of appetite, nausea, vomiting Those on longtern kidney dialysis, health care workers, those having unprotected sex, drug addicts, those who have visited unrepeatable tattoo parlors Those who are infected with HIV, being on hemodialysis, having multiple sexual partners, having sexual intercourse with men, having a parent who has the disease Sterilizing instruments used, receiving the HBV vaccination Acute hepatitis needs no treatment other than careful monitoring of 1 Hepatitis D HDV Only found in people who carry the HBV Hepatitis E HEV Contaminated drinking water Abdominal pain, dark colored urine, fatigue, jaundice, joint pain, loss of appetite, nausea, vomiting Jaundice, anorexia, enlarged or tender liver, abdominal pain, nausea, vomiting, fever Drug addicts, babies who are carried in a mother with the virus, anyone with HBV, having sexual intercourse with men, receiving blood transfusions Those who practice poor sanitation in large areas of the world and shedding of the hepatitis E virus in feces Not sharing needles and practicing safe sex Sterilizing instruments used, receiving the HBV vaccination To remove the virus from the blood and reduce the risk of cirrhosis and Medication Prevention is the most effective approach against the disease There is no available treatment capable of altering the recommended liver and other body functions with blood tests. You should get plenty of bed rest, drink plenty of fluids, and eat healthy foods liver cancer that can result from long-term HCV infection, can treat with medication course of acute hepatitis (Nelms et al., 2011, p. 447-450) 2. Describe hepatitis C to Ms. Wilcox as you would a patient. Hepatitis is the inflammation of the liver that can come from many sources such as toxins, certain drugs, some diseases, heavy alcohol use, and bacterial and viral infection. Specifically, you have been diagnosed with hepatitis C, which is a contagious liver disease that ranges in severity from a mild illness lasting a few weeks, to a serious, lifelong illness that attacks the liver. It results from infection with the Hepatitis C virus (HCV), which is spread primarily through contact with the blood of an infected person, although it can also spread through sex with an infected person and from mother to baby during childbirth (National Institutes of Health [NIH], 2012). Hepatitis C can be either acute or chronic, depending on if the virus remains in the body. Acute Hepatitis C virus infection is a short-term illness that occurs within the first 6 months after someone is exposed to the Hepatitis C virus. For most people, acute infection leads to chronic infection. Chronic Hepatitis C is a serious disease than can result in long-term health problems and should be treated as soon as possible (Center For Disease Control and Prevention [CDC], 2012). 3. What signs and symptoms does Ms. Wilcox have? Ms. Wilcox is experiencing fatigue, muscle and joint aches, malaise, vague upper right quadrant pain, nausea, weight loss, and anorexia. Ms. Wilcox is also experiencing upper right abdominal guarding and elevated liver enzymes (Nelms et al., 2009, p. 183-194). 4. Are there any other typical signs and symptoms of hepatitis that Ms. Wilcox does not have? Many people infected with HCV do not have any symptoms. However, when symptoms are present, they range from mild to severe. Some symptoms that Ms. Wilcox is not experiencing are dark urine, headache, fever, clay-colored bowel movements, and jaundice (CDC, 2012). 5. Describe how the symptoms of hepatitis are related to the pathophysiology of the disease. The liver is integral to most metabolic functions of the body and performs more than 500 tasks, including carbohydrate, protein, and fat metabolism, storage and activation of vitamins and minerals, and action as a filter. It is no wonder that when the liver is malfunctioning or is in a disease state, that many symptoms 2 arise. Symptoms occur because of the reduced functions of the liver when hepatitis or any disease state is present (Nelms et al., 2011, p. 447-450). 6. Teresa Wilcox is devastated by the diagnosis. She tells Dr. Horowitz that she’s never had a blood transfusion or been exposed to blood products. She has never used IV drugs, but did inhale cocaine once or twice at parties in college. She has had several sexual partners, and the only time she has come into contact with any kind of needles was when she had her naval pierced six months ago. How, most likely, did Terri contract hepatitis C? Ms. Wilcox most likely contracted hepatitis C six months ago, while getting her naval pierced. Hepatitis C is usually spread when blood from a person infected with the hepatitis C virus enters the body of someone who is not infected. Today, most people become infected with the hepatitis C virus by sharing needles or other equipment to inject drugs (CDC, 2012). The place of business where Terri had her naval pierced could have not properly cleaned her piercing utensils or could have reused the same needle on Terri as someone with hepatitis C. II. Nutrition Assessment 7. Calculate the patient’s percent UBW and BMI, and explain the nutritional risk associated with each value. No usual body weight was provided so the Hamwi formula was used. Hamwi= 100 lbs + (5 x 9)= 145 lbs= UBW % UBW= 130 lbs/145 lbs= .90 x 100%= 90% % change= 100- 90%= 10% Ten percent is a significant amount of weight to lose. More information would be needed to determine the true severity of the situation since the case study does not offer a time frame for the weight loss (Nelms et al., 2011, p. 47-48). BMI=[weight(kg)]/[height(m2)] Weight= 130/2.2= 59.0 kg Height= ((69x2.54)/100)2= 3.07 m2 BMI= 59.0 kg/ 3.07 m2= 19.2 kg/m2 This BMI is considered within the normal range. If Terri continues to lose more weight and her BMI decreases to less than 18.5 kg/m2, then she could be placed in the underweight category and at risk for many health complications including chronic obstructive pulmonary disease, cancer, and congestive heart failure (Nelms et al., 2011, p. 48). 8. Because resting energy expenditure varies with liver disease, indirect calorimetry is recommended. However, you do not have access to this means of measurement. How would you estimate Ms. Wilcox’s energy and protein requirements? 3 Typically indirect calorimetry is the gold standard to calculate energy expenditure. Because this form of estimate is not widely available, energy estimate equations are often applied in the hospital setting. I would estimate Terri’s energy requirements using the Mifflin-St. Jeor equation. This equation is the most recent edition and has been validated in over 10 different studies in the last decade (Nelms et al., 2011, p. 59). To estimate Ms. Wilcox’s protein requirements, a range of 1.0-1.5 grams of protein per kilogram of body weight per day should be used for those in metabolic stress, trauma, or disease (Nelms et al., 2011, p. 61). 9. Identify any potential nutrition problems regarding micronutrient requirements. Provide the rationale for why theses micronutrients are of concern. Since the liver plays a vital part in nutrition and the digestive systems, those with hepatitis C should consume adequate micronutrients. Iron, copper, some vitamin B vitamins, vitamin C, and the fat-soluble vitamins A, D, E, and K are all stored in the liver. If the liver is not functioning correctly, then the role of these micronutrients may be severely compromised. Fat-soluble vitamins may not be converted into the active forms needed in the body and red blood cells may be negatively affected of iron, copper, and vitamin B12 are not properly used. This may cause many deficiency symptoms and severe complications (Dietitians of Canada, 2012). 10. Calculate this patient’s total energy and protein needs using the Mifflin-St. Jeor equation. The Mifflin-St. Jeor equation can be used to estimate Terri’s daily energy needs (Nelms et al., 2011, p. 60). Mifflin-St. Jeor= 10 x (kg) + 6.25 x (cm) – 5 x (age) – 161 10 x (65.9) + 6.25 x (175.3) – 5 x (22) – 161= 1,483 kilocalories= REE Activity factor= 1.5 for the average adult female who is not sedentary TEE= 1.5 x 1,483= 2,225 kilocalories per day or a range of 2,200-2,300 Protein needs: 1.0-1.2 grams of protein for every kilogram of body weight= 65.9- 79.1 grams of protein 11. Using the patient’s usual dietary intake, help her plan a menu. Usual Diet Suggested Substitution Kilocalories Protein (grams) 1½ cup Sugar Frosted Flakes 318 8.6 ½ cup 2% milk 1½ cup high fiber oatmeal (no sugar added or low sugar) 1 cup 1% or skim milk 83 8.3 1 banana No change 27 1.3 1 cup calcium fortified orange juice ½ cup calcium fortified orange juice 57 0.8 4 Iced tea Water 0 0 Cheeseburger Grilled chicken sandwich on 100% whole wheat bun, mustard, and veggies Water 419 32.4 0 0 176 3.0 3 ounces shrimp Baked sweet potato wedges 3 ounces shrimp 122 23.5 1½ cup vegetables No change 45 3.7 1 cup steamed rice 1 cup steamed brown rice 1 cup 1% or skim milk 684 14.7 83 8.3 1 cup sliced watermelon 46 0.9 2,138 kilocalories 105.6 grams 12 ounces Diet Coke French fries Water 4 cookies Total: *All food must be thoroughly cooked to proper internal temperatures and handlers must make sure to wash their hands to minimize germs. (FitDay.com, 2011) 12. Identify nutrition problems within the nutritional domain using the correct diagnostic term. Nutrition problems include: Inadequate oral intake (NI-2.1) Inadequate fluid intake (NI-3.1) Inadequate protein-energy intake (NI-5.3) (IDNT, 2011) 13. Examine the patient’s chemistry report. What values would steer Dr. Horowitz towards the patient’s diagnosis? Terri’s chemistry panel reveals that there are several lab values that are abnormal. Her ALT, AST, bilirubin, alkaline phosphatase, and LDH values are all high. In addition, the hematology panel reveals a high PT and WBC, and a low HGB, HCT, and platelet count. Lastly, the urinalysis reveals protein in Terri’s urine. All of these values would point Dr. Horowitz towards the patient’s diagnosis of hepatitis C (Lab Tests Online, 2012). 14. What do the values measure, and what is their relationship to liver disease? Lab Value ALT (high) AST (high) Bilirubin (high) What It Measures Measures and detects liver damage Measures and detects liver damage To screen for or monitor liver 5 Relationship To Liver Disease All types of liver disease can cause All types of liver disease can cause Cirrhosis, alcoholic liver disease, Alkaline phosphatase (high) LDH (high) PT (high) WBC (high) HGB (low) HCT (low) Platelet count (low) Protein in urine (1+) disorders or hemolytic anemia To screen for or monitor treatment for a liver or bone disorder Measures tissue damage Measures how fast the blood clots Measures the number of white blood cells in the blood Measures the hemoglobin content of the blood Measures the portion of blood that is red blood cells Measures the number of platelets in the blood The amount of protein that spills over into the urine or viral hepatitis can cause Liver disease or liver cancer can cause Liver tissue damage can cause Inflammation from liver disease can cause Inflammation from liver disease can cause Inflammation from liver disease can cause Inflammation from liver disease can cause Viral infections such as hepatitis C can cause Inflammation from liver disease can cause (Lab Tests Online, 2012) 15. The results of the anti-HCV and HCV RNA tests that Dr. Horowitz ordered were positive. What does this mean? A positive anti-HCV test detects the presence of antibodies to the hepatitis C virus, indicating exposure to HCV. A positive HCV RNA test detects and measures the number of viral RNA particles in the blood (Lab Tests Online, 2012). Both of these tests are used to indicate exposure to the HCV and can be used to diagnose it in patients. 16. Once the diagnosis of hepatitis C is made, the physician orders 3-MU interferon alfa-2b sq qd, and Rebetol 200 milligrams po bid. What are these medications, and what do they do? 3-MU interferon alfa-2b used to prevent tumor cells or viruses from growing inside the body (NIH, 2102). It can be used in combination with other medications. This medication is taken in a subcutaneous injection, once daily. Rebetol is a brand name of Ribavirin and is used to treat hepatitis C. It works by stopping the virus that causes hepatitis C from spreading inside the body. It will not be affective unless taken with another medication, such as an interferon, and that is why Dr. Horowitz prescribed it in combination with the 3-MU interferon alfa-2b (NIH, 2012). This medication is taken in 200-milligram doses by mouth, twice daily. 17. What are nutritional side effects of interferon and ribavirin? Most people taking interferon and ribavirin have side effects from the drugs. The most common include fatigue, fever, muscle aches, headaches, anxiety, skin rash, depression, nausea, diarrhea, and anorexia. Specifically, nutritional side effects include, nausea, diarrhea, and anorexia. Monitoring of severe symptoms and management of all symptoms of side effects is critical to the effective completion of the therapy that the drugs provide (Department of Veteran Affairs, 2012). 6 18. Given these side effects, what can the dietetic professional do to help the patient maintain positive nutritional status? To help the patient maintain a positive nutritional status, the dietetic professional can instruct the client on how to consume their meals. For nausea, the patient can take their medication with meals or eat smaller, more frequent meals. In addition, consuming ginger can help and can be found in ale, tea, and ginger snap cookies. The patient should also avoid smells and foods that trigger nausea. For anorexia, eating smaller, more frequent meals may be helpful. Nutritional supplements like Ensure and nutrient bars and snacks with protein can pack calories in little space. Lastly, for diarrhea, an oral anti-diarrheal agent can be administered as long as symptoms exist. Also, caffeine and lactose containing beverages and high-sugar soft drinks should be avoided. Boiled rice, apples or applesauce, bananas, oatmeal, and bulking agents such as Metamucil can help solidify stool (Department of Veteran Affairs, 2012). 19. List nutrition problems with in the clinical domain using the correct diagnostic term. Nutrition problems include: Food-medication interaction (NC-2.3) Altered nutrition-related laboratory values (NC-2.2) Impaired nutrient utilization (NC-2.1) (IDNT, 2011) 20. Ms. Wilcox tells you that a friend suggested she use milk thistle to help fight the hepatitis virus. What would you tell her? Although this CAM is generally well tolerated, Terri does not know if she is allergic to milk thistle. Because she has an allergy to penicillin, I would caution Terri with its use because people with one allergy are more likely to have another allergy. In addition, more research is needed to prove the actual effectiveness of this CAM and its claims to benefit the liver (NIH, 2012). 21. List any potential problems with the behavioral-environmental domain. Nutrition problems include: Food and nutrition related knowledge deficit (NB-1.1) Not ready for diet or lifestyle change (NB-1.3) Limited adherence to nutrition-related recommendations (NB-1.6) (IDNT, 2011) III. Nutrition Diagnosis 22. Select two high-priority nutrition problems and complete the PES statement for each. 1. Inadequate oral intake related to nausea and anorexia as evidence by 24-hour recall and weight history. 2. Impaired nutrient utilization related to hepatitis C diagnosis as evidence by altered chemistry, hematology, and urinalysis lab values. 7 (IDNT, 2011) IV. Nutrition Intervention 23. As you assess Teresa Wilcox’s nutritional status, what are your concerns? I am concerned that Terri will have trouble taking in adequate calories, nutrients, and fluids due to the pain, nausea, and anorexia she is experiencing. These symptoms can make it very hard for the patient to find motivation to eat and stay hydrated. Terri’s 24-hour recall revealed that she had not consumed much and I worry that this will only continue while her symptoms last. If this occurs, then Terri’s illness will worsen and she will continue to lose weight. Both of these things are highly undesirable when trying to treat a serious virus. In addition, I worry that Terri’s hectic lifestyle will interfere with her ability to make significant changes in her eating patterns. 24. Dr. Horowitz requested your consultation to order the patient’s diet. What do you recommend? I recommend a diet that will spare the liver and provide it with the nutrients that are needed for regeneration, maintenance, and healing. Terri needs adequate fluids, good nutrition, and avoidance of alcohol to combat her diagnosis (Nelms et al., 2011, p. 450-451). I would encourage Terri to consume a diet adequate in energy, protein, and micronutrients. Terri should be on a regular meal schedule, with her meals spread out into six small feeds a day, to help with her symptoms of nausea, diarrhea, and anorexia. Terri should consume about 2,100-2,200 kilocalories and 60-90 grams of protein daily. Alcohol should be avoided for the time being. 25. How will you be able to determine whether this diet prescription is appropriate? Through thorough monitoring and evaluation I will be able to determine if the diet prescription written for Terri is appropriate. First, subsequent visits from Terri will use her baseline lab values to monitor changes in her chemistry, hematology, and urinalysis panels. In addition, her anthropometric, BMI, and weight status data will be monitored in a similar way. If Terri is losing weight, then more calories and nutrients will be added. If she is gaining weight, then the opposite action will be taken. These pieces of data will give an accurate picture of how the diet prescription is working for Terri. 26. For each of the PES statements that you have written, establish an ideal goal (based on the signs and symptoms) and an appropriate intervention (based on the etiology). 1. Goal: To eat a balanced diet with adequate calories, protein, and micronutrients daily. Some intervention strategies would be to eat smaller, more frequent meals, avoid foods or smells that trigger nausea, and avoid caffeine, lactose, and high sugar containing beverages. 8 2. Goal: To improve altered chemistry, hematology, and urinalysis lab values with adequate nutrition. An intervention strategy would be to give basic nutrition education to show Terri which micronutrients she should be increasing in her diet and supplementing with outside sources. 9 References Hepatitis C.
